IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 37,789, dated February24. 1863.

To all whom it may concern Be it known that we, P. B. REYNOLDS and L.

p O. REYNOLDS, of Prophetstowmin the county of VVhiteside and State ofIllinois, have invented a new and useful Improvement in Corn-Oultivators; and we do hereby declare that the following is a full,clear, and exact description of the same, reference being had totheaccompanying drawings, forming part of this specification, in which-Figure 1 is a perspective view of our corncultivator. Fig. 2 is alongitudinal section through one of the beams.

The same letters of reference in the several figures indicatecorresponding parts.

The nature of our invention consists in an arrangementof an approximateV-frame swin ging tree, draft-rods, adjustable draft-rod bars,perforated adjusting-plates, swiveling cultivator standards or stocks,and bent sustainin g-bars, all constructed for operation to geth er, ashereinafter described.

It also consists in the arrangement, upon adjustable beams of the frame,of two or more pairs of perforated adj usting platesforthe purpose ofsetting the swiveling stocks of cultivator-teeth.

It also consists in the arrangement of the bent sustaining-bars,adjustable side beams, and angular slots of the middle and rear beams.

It also consists in the arrangement of the single-tree under and uponthe rear beam, and having its draft-rods run forward through adjustablebars of a front cross-piece.

It also consists in the arrangement of the circular adjusting-plate,square upper end of the cultivator-tooth stock, round portion, and theside beam and sustaining-bar.

To enable others skilled in the art to make and use our invention, wewill proceed to describe the same with reference to the drawings.

A B G D E designate the five beams which constitute the frame of thecultivator. These beams are placed together so that they form a figurevery closely approximating to the letter V. To the beam A, which is thelongest cross beam, and is at the widest or front end of theframc, theangular side beams, B G, are pivoted, as at a 'a. These beamsB O arealso connected, by means of angular slots b b and, c c in the middlecrossbeam, D, and end cross-beam, E, and screw-boltsd d and e e, to themiddle cross-beam, D, and rear cross-beam, E, in the manner shown. Thismode of connection and slots 8 s in the side beams, B O, admits of theside beams being moved nearer together or farther apart on their pivotsa a. Under the side beams, B O, bent bars EF are arranged, and theirends extended under the front and rear bea1ns,A E, and attached firmlyto the pivots a a and screw-bolts e e. 7

Through the beams B C, and also the sustaining-bars F F, round holes f fare cut vertically, and through these holes inclinedstandards or stocksG G G are passed loosely. The termini t t of these stocks are made fiator square, while the portions below the same are round. G G receive uponthem semicircular plates H H, said plates being confined in place bypins 9 g, as shown. The plates H H, have lever ends h h,and areperforated vertically with a series of small adjusting-l1oles,ii, whichare formed on a circle struck from the axis of the stocks G G. In one oranotherof these holes, accordingly as an adjustment of the stocks ismade, a pin, j, is inserted, said pin enteringa hole, k, formed in thebeams B G, as shown.

To the under side of the rear beam, E, a single-tree, I, is pivotedcentrally, as at I. From the ends of this single-tree draft-rods J Jextend forward beyond the front-beam, A, and pass loosely throughvertical bars or hangers K K, which extend down through a fixedcrosspiece, L, of theframe. The hangers have a series ofadjusting-holes, m m, punched horizontally in them, and through one oranother of these holes a pin, a, is passed, accordingly as thedraft-rods are set. On the front ends of the draft-rods whiflietrees M Mare hinged, as usual. 5

Y On the front and middle beams of the-frame hounds N N are arranged,and between the frontends of the same a tongue, 0, is fitted and hung bya kin g-bolt, so as to only be able to turn on the bolt in a downwarddirection.

From the middle beam handles P P rise and extend back beyond the rearbeam, being supported and braced by a standard, a screw-rod, and bars,as indicated by letters Q R S.

The square upper ends of the stocks The machine thus constructed isprovided with anyform of cultivator tooth, shovel, orhoe at the lowerends of its stocks or standards.

In the use of the machine two horses are attached to its tongue andwhiffletrees, and the horses walk respectively onopposite sides of a rowof corn, or with one row between them and tworows outside of them. Thusthe central row is billed on bothsides and the other two rows on oneside at each passage across the field.

In case it is desired to set the shovels so that they will turn the soiltoward or from the corn, the circle-plates are unpinned, and by theirlever. ends h,'the stocks, with shovels attached, are turned or adjustedas desired, and the plates again pinned firmly.

The single-tree by being in rear of all of the shovels allows of longdraft-rods being em- 1ployed, and by having such rods and providing forregulating their draft, as described, the whole series of cultivatorteeth or shovels are kept down to the work. I

Ihe frame by being sustained by the bent bars F F is sufiiciently strongfor the work anddraftbrought upon it-,'and at the same time the stocksare sustained midway of their length, and the side beams, stocks, andbars can be adjusted together.

I The separate circular plates answer for converting-the machine intoaright and left cultivator, orfor'turning one portion of the shovels sothat they throw up soil to the hill of corn,

and-.for turning another portion so that they throw 0d the soil from thehill of corn.

The angular slots b c and the slots 8 .9 allow the rear portion of thecultivator to be constructed or expanded as necessity may demand.

The shovel-stocks might be passed upzon the side of the side beams, B C,and confined by clamp-bars.

Our machine answers a most excellent pur pose on our Western lands,.andsaves the services of many hands. Our machine might be mounted uponwheels and a crank-axle and have a seat for a driver. The bar L mightberemoved and the bars K be passed down through the front beam, A.

What we claim as our invention, and desire to secure by Letters Patent,is-- 1. The arrangement, upon adjust-able beams B C, of two or morepairs of perforated leveradjusting plates H h i, for the purpose ofadjusting two or more pairs of shovelstooks, G G t f, in the manner andfor the purpose de scribed.

2. The arrangement of the bent sustainingbars F F, side beams, B (l, andslots 1) c s s, in the manner and for the purpose described.

3. The arrangement of the frame A B GD E, single-tree I, draft-rods J J,adjust-able hangers K K, perforated lever-adjusting-plates H H Hv H,swiveling square or flat top standards Gr G, bent sustaining-bars F F,and slots b as, the whole constructed and operating together in themanner and for the purposes described.
